CAN ENDING AND SEAMING MACHINE.

SPECIFICATION forming part of Letters Iatent No. 294,065, dated February26, 1884.

Application filed June 8, 1883. (No model.) I A a I To all whom, it mayconcern.-

Be it known that we, EDWIN NORTON and JOHN G. HonesoN, citizens of theUnited States, residing in Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Can Ending and'Seaming Machines, of which the following is a specification,

The object of the present invention is to provide an automatic machinefor applying the heads or ends to sheet-metal cans and seaming the same.

The invention consists, in connection with suitable molds or devices forclamping and holding the cau-bodies while the heads are being appliedand seamed thereon, of mechanism for feeding the can-bodies to theclamping device, suitable pistons or devices for forc ing the can-headsupon the can-body, mechanism for feeding the can-heads, mechanism forseaming the can-heads to the can-bodies, and mechanism for dischargingor delivering the cans from the machine.

In the accompanying drawings, which form a part of this specification,we have shown a machine embodying our invention, which is particularlyadapted to unite the can-heads to the can-bodies by a form of seamcommonly known as an exterior squeezed or cri 1n ped very much employedin square, rectangular, or

pyramidal cans used for packing cooked meats and other articles. Thisform of seam, when properly made, practically prevents the contents ofthe can from coming in contact with the solder in the seam, forthe'reason that the parts or flanges of theseam are tightly squeezedtogether and the solder applied from the outside of the can. 1

As will be understood from the drawings, the mold or clamp in which thecan-bodies are held is made in two parts or halves, one part beingsecured to a reciprocating piston or plunger, andthe other part (or aseries of them) being mounted on the periphery of a revolving wheel.This wheel is'revolved intermittently, so as to bring the part-molds onits periphery successively in front of the part mold on the piston, whenthe forward 1nove- 5o ment of the latter clamps the can-body securelyseam or joint, the same being a form of seam in the mold while the headsare being applied thereto and the seams formed. The can-bodies areautomatically delivered into the part-molds on the wheel from a suitabledelivery chuteor mechanism, and retained and carried in said molds intoposition in front of the reciprocating half-mold as the wheel revolves.The can heads or ends are fed into the machine by suitable chutes ordevices, and delivered in front of the mold, one at each end of the can-6c body. The can-heads are applied and forced on the can-body, while itis held in the mold,

by reciprocating pistons or devices. The periphery of the piston-headconforming to the interior of the countersunk can head or endconstitutes the mandrel or support against which the exteriorcrimping-jaws or seaming devices act in squeezing the flanges or partsof the seam closely together, or otherwise forming or partially formingthe seam. The squeezing or crimping jaws are mounted on a slide or framewhich is reciprocated either with or independently of thecan-he'ad-applying piston. The purpose of reciprocating thesqueezing-jaws or seam-forming devices is to bring them in position overor around the projecting end or flange of the can-body, so that they maybe closed together upon the canhead and form the seam. It is then ofcourse necessary to retract them with the pistonapplying head, in 'orderthat the mold-wheel may again revolve and bring another partmold inposition. It will be observed that the end or flange of the can-bodywhich is united or seamed with the flange of the canhead projects out ofthe mold, the mold being shorter than the can-body. The crimpingjaws orseam-forming devices may be closed together or operated by cams ormechanisms similar to those employed to operate 0 the reciprocatingpart-mold. By giving the squeezing-jaws and the periphery of thepiston-head bevel-faces, the squeezed seam may be turned out at anydesired angle to the body of the can. It will be noticed that the act of5 bendingthe seam out at an angle somewhat diminishes the length orheight .of the can-body, and this'fact has occasioned considerabledifficulty and irregularity in the operation of the machines or devicesheretofore commonly. em- IOO ployed to form these squeezed externalseams, as in such devices the can-body was held in position while beingoperated upon by the jaws by simply placing it between two par allel endplates or disks. It is obvious that, if these end plates were adjustedto fit the length of the can body and properly hold it while the firsthead was being applied, and the seam formed and turned out, when theoperator came to apply the other head, the plates would be too far apartto properly fit the thus shortened can-body, and for this reason thedevice would be caused to do defective work This difficulty, however, isobviated in some factories by employing one machine to apply the firsthead to the can-body and another machine, differently adjusted, to applythe other head; but this of course necessitates increased labor and morehandling of the cans. By our invention or machine the can-bodies areclamped and held at their middle portion in a mold, so that both headsmay be applied and seamed simultaneously, and so thatthe diminishedlength of the can-body caused by turning the seams at an angle in no wayeffects the operation of the machine in applying or seaming either ofthe heads.

In the drawings, Figure 1 is a plan view of the machine. Figs. 2 and 3are sections on lines 2 2 and 3 3, respectively, of Fig. 1. Fig. 4: is adetail sectionalview similar to Fig. 3, showing the squeezing-jaws open.Fig. 5 is a cross-section on line 5 5 of Fig. 1. Figs. 6, 7, and 8 aredetail sectional views, showing the different positions of thecrimping-jaws and piston in successive stages of the operation ofapplying the can-head and forming the seam. Fig. 9 is a View similar toFig. 8, except that the crimping-jaws and pistons have bevelfaces, so asto turn the seam out at an angle.

A represents the frame of the machine.

Bis a wheel, provided with half or part molds b on its periphery, intowhich the canbodies are received from a delivery-chute, 0, one by one,as the wheel revolves. The periphery a of the wheel between thepart-molds 1) serves to support the can-bodies in the delivery-chuteuntil one of the molds or pockets comes under the chute,when a can-bodydrops therein. As the wheel revolves, the can-bodies are carried inthese part-molds in front of a reciprocating or ind'ving part-mold, b,the same being retained in the partmolds b by means of a curved guard,B, which extends from near the delivery-chute down in front of thereciprocating half-mold in a slot therein. Curved guides B on each sideof the wheel serve to center or adjust the can-bodieslongitudinally inthe mold b. The wheel B is driven intermittently, and is stopped andheld stationary when each of the part-molds is brought in front of thereciprocating part-mold, while the latter is moved forward to clamp thecanbody and hold it firmly while the can-heads are being applied andseamed upon the body. The half-mold Z) is secured to a two-partcrosshead, D, which slides back and forth in suitable gibs, D, securedto the frame of the machine, and which is operated by cams D-'. Thecan-heads are fed to the machine by chutes E E one on each side of thewheel which deliver the same at each end of the can-body clamped in themold and in front of reciproeating piston-heads G and G, by which theyare forced upon or applied to the can-body. The crimping-jaws aremounted on a reciprocating block or frame, 'H,which slides back andfor-thin suitable gibs, H, secured to the frame of the machine. rocatedby means of a grooved cam-wheel, 71

The block H is reeipoperating upon the wrist-pin or roller h, se-

cured to the block H. The mold 127) is shorter than the can-body If, sothat the ends of the can-body will project out beyond the mold asuificient distance to leave room or stock for the seam. The can head Z)is countersunk, so as to fit inside the can-body, and is provided withan overlapping flange, If, which is bent or formed into a seam, with thecanbody on the flange thereon. The crimping jaws F F F F are mounted onthe recipro;

eating block H, so as to enable them to be moved into position over theend of the canbody to crimp and form the seam, and to be afterwardretracted, so that the wheel may revolve. The crimping-jaws F Fl F areeach mounted in suitable ways or gibs, I, secured to the reciprocatingblock H. These crimping-jaws are closed together or operated back andforth in their guides or ways by means of cams K and K on the shaft Kwhich rethe crimpingjaw F is secured. The jaws F and F are operated fromthe jaw F by means of slides L, which are provided with cams or slots Z,in which engage pins Z, fixed in the jaws F and F, the slides L beingconnected to the jaws F by means of an arm, Z secured to the jaw F. Thearm Z is secured at each end to the slides L by adjusting-screws Z sothat the slides may be accurately adjusted to give the proper movementto the jaws F and The jaw F" is operated by means of a bent lever, Z,which is pivoted to a bracket on the block H, and provided with a cam orslot, 1, which engages with a pin, Z, fixed in the jaw F The. other armof the lever is connected to the slide L by means of a rod, P, whichshould be provided with a turn-buckle for adjusting the movement of thejawF. L represents the gibs in which the slides L reciprocate. In thisway all the crimping-jaws are simultaneously operated. The pistoirheadsG and G are secured to suitable sliding heads, 9, which reciprocate ingibs g, secured on the sliding block or frame H. These sliding heads 9are actuated by means of the crankwheel 9 and the crank-arm g, andslotted links 9" and 9 which are connected to the head 9 by means of apin or bolt, 9. The pin ICO IIO

K, which connects the cross-head K with the crimping-jaw F, is made longenough to permit of the reciprocating motion of the frame H, on whichthejaw F is mounted.

Any ordinary mechanism for intermittently revolving the wheel B may beemployed-as, for example, a rock-shaft, a, and ratchet mechanism on theshaft of the wheel B, which should also be provided with a stop or checkwheel for holding the same rigidly in position while the can-head isbeing applied.

Suitable devices for intermittently operating the wheel 13, the pistonsG and G, and the reciprocating half-mold we have fully shown anddescribed in Letters Patent No. 274,363, dated March 20, 1883,heretofore granted to us for improvement in can-ending machine,

and as such operating mechanism does not constitute the novel featuresof the present invention we have not deemed it necessary to herein againdescribe the same at large. For a more full description of these partswe make reference to said Patent No. 274;363.

Instead of the movable jaws herein shown for squeezing the parts of theseam firmly together, the squeezing or seam-forming mechanism mayconsist of fixed or rigid jaws, in which case they should be madeintegral with the part-molds b and b, and the piston-heads G G should beprovided with a shoulder projecting over the flange of the can-head, asshown in Fig. 9,'the forward movements of the piston-heads in that caseserving not only to apply or force the can-head upon the canbody, butalso to press or squeeze the parts of the seam together and to turn theseam out at an angle to the can-body.

The can-head-delivery chutes E and E are mounted on the reciprocatingblocks or carriages H. When the piston-heads G G make their forwardstroke to apply the can-heads to the can-body, they support thecan-heads in the chutes E and E. When the pistons are retracted, thecan-heads drop down in front of the pistons, so that they are fedautomatically to the machine.

P represents the dischargechute, into which the headed and seamed cansfall from the wheel B as it revolves.
